Fix Engine always reading in notes from DiskStorage

* One of the engine's tasks is to cache all notes in memory, and only
  store notes upon explicit call to engine.SaveNote(). Prior changes to
  a note are reflected in-memory, but will not be persisted until a note
  is saved.

* Before this comments notes where read-in repeatedly from IStorage,
  which caused reading in the directory very often.
Fix FileSystemSyncServer manipulating the engines notes

* The FileSystemSyncManifest is not allowed to change the note's text
  for convenience reasons as this change persists in-memory and will
  affect all other code areas that will access the engine's notes.
* Removed the hack for now, clean implementation should operate on a
  cloned set of notes in FileSystemServerServer
